“…However, this species displays greater mtDNA than nuclear DNA structure on Borneo (Lim et al 2017). It also has complex relationships with Pin-striped Tit-Babbler M. gularis (Cros & Rheindt 2017), its closest relative outside of Borneo, decreasing the reliability of conclusions based on a few mtDNA comparisons of a limited sample of specimens. White-necked Babbler Stachyris leucotis.-The Meratus, Sarawak and Sabah populations appear to form distinct clades.…”

BioOne site, where you will also find the previous volume, 137. We look forward very much to working with the BioOne team in establishing a strong web presence, for the benefit both of readers of the Bulletin and authors and potential authors. The recent Newsletter (No. 9) spells out in greater detail the service provided by BioOne. Please let us have any comments and suggestions about these new arrangements. In addition to our online presence and Newsletters, we continue to meet regularly as a Club and during 2018 we shall have four 'Barley Mow' meetings plus a joint two-day meeting in Liverpool with the Society for the History of Natural History. I hope you will have seen the published details and will join us for what promises to be a stimulating and enjoyable event. The Annual Review Meeting of the Club will be held in the upstairs room at the Barley Mow, 104 Horseferry Road, Westminster, London SW1P 2EE, at 5.30 pm on Monday 21 May 2018, Papers for the meeting including the financial report and accounts will be issued shortly. The Review Meeting will be followed at 6.30 pm by Dr Bård Stokke's talk on Host selection by the Common Cuckoo. Chris Storey The 988th meeting of the Club was held on Monday 6 November 2017 in the upstairs room at the Barley Mow, 104 Horseferry Road, Westminster, London SW1P 2EE. Fifteen friends were recorded as present and three visitors. Friends attending were Miss H. Baker,

“…Given the Isler criterion's known conservatism and susceptibility to type II errors under low sample sizes (Isler et al 1998, Rheindt et al 2011, Cros & Rheindt 2017, we believe that the detection of complete diagnosability in at least one character between Rote and Sumba Myzomelas points to deep levels of bioacoustic differentiation in two species that have remained morphologically similar.…”

“…In our classification of call types, we interpreted an unbroken vocal segment as an "element", whereas a "motif" was taken to be a collection of one to multiple elements that are repeated in an almost identical fashion (Rheindt et al 2011, Harris et al 2014 Vocal parameters were also analysed using Isler et al's (1998) criterion for bioacoustic species delimitation (henceforth referred to as the Isler criterion). The Isler criterion has previously been applied successfully to distinguish among vocally divergent lineages of Asian and AustraloPacific doves, nightjars, bulbuls, owls, and babblers (Sangster & Rozendaal 2004, Rheindt et al 2011, Garg et al 2016, Gwee et al 2017, Cros & Rheindt 2017 (Fig. 3), a bioacoustic comparison using the Isler criterion was not performed based on low sample size across these call types.…”

The avifauna of Rote Island in the Lesser Sundas is not well studied and generally considered to be similar to that of adjacent Timor Island. However, some cases of bird endemism have recently been documented on this island. A population of Myzomela honeyeater is one such example. First observed in October 1990, it has been subsumed with Myzomela dammermani from Sumba Island given its superficially similar appearance. Based on extensive morphological inspection and bioacoustic analysis, we here describe this population as a new taxon to science. Apart from previously overlooked plumage distinctions, the new taxon bioacoustically differs from M. dammermani in the presence or absence of several unique call types and considerable differences across two parameters in shared call types. Considering the importance of bioacoustics in avian species delimitation, we propose that the new Rote Myzomela be considered a distinct species. Given continued habitat conversion across its small range, we propose the International Union for Conservation of Nature and Natural Resources (IUCN) threat status Vulnerable for the species.

“…where t i refers to the t-score at the 95 th percentile of the distribution for n -1 degrees of freedom. The Isler criterion was initially devised for New World antbirds (Isler et al, 1998), but has been applied across various songbirds (Cros & Rheindt, 2017;Prawiradilaga et al, 2018;Gwee et al, 2019b) and non-oscines (Sangster & Rozendaal, 2004;Gwee et al, 2017;Gwee et al, 2019a).…”

Morphological traits have served generations of biologists as a taxonomic indicator, and have been the main basis to delineate species for museum taxonomists for centuries. Widespread awareness of the importance of behavioural characters, such as vocalizations, has arisen much more recently, and the relative importance of these different traits in the speciation process remains poorly understood. To shed more light on the interplay between morphological and behavioral traits in the speciation process, we generated a draft genome of a cryptic Southeast Asian songbird, the Limestone Wren-babbler Napothera crispifrons, and re-sequenced whole genomes of multiple individuals of all three traditional subspecies and a distinct leucistic population that had previously been misinterpreted as a plumage polymorphism. We demonstrate strong genomic and mitochondrial divergence among all three taxa, pointing to the existence of three species-level lineages. Despite its great phenotypic distinctness, the leucistic population was characterized by shallow genomic differentiation from its neighbor, with only a few localized regions emerging as highly-diverged. Quantitative bioacoustic analysis across multiple traits revealed deep differences especially between the two taxa characterized by limited plumage differentiation. Our study demonstrates that speciation in these furtive songbirds is not governed by the evolution of marked color differences, but is regulated by an interplay between color and bioacoustic traits. Extreme color differences can be anchored in few genomic loci and may therefore arise and subside rapidly.
